Description:
Type: Panama. Colón: Loma de la Gloria, near Fató (Nombre de Díos), alt. 10-14 m, Aug 1911 (fr), Pittier 4093 (holotype, US 679189; isotype, GH)
Description: Trees, small, to 10 m x 25 cm, known to flower at 1.5 m; leaf-bearing branches (4-)5-8(-12) mm diam., the leaves tightly grouped at ends. Leaves: petioles (20-)60-150(-250) x 1.5-3 mm, subterete in cross section; blades elliptic, narrowly ovate, or lanceolate, (11-)18-27 (-43) x 5-13(-15) cm, glabrous, chartaceous, the base acute, cuneate, obtuse or rounded, the margins serrulate, the apex acuminate; secondary veins in 10-21 pairs. Inflorescences cauline, contracted, racemose, glabrous, puberulous, or occasionally rusty-tomentose, with 3-7 flowers, the rachis 8-50 mm long; pedicels 15-40 mm long, subtended by a single caducous bract, and bearing near middle 2 ovate bracteoles usually fused at bases, 2-6 x 3-8 mm. Flowers 13-18 cm diam.; petals 8, narrowly obovate or oblanceolate, 60-85 x 30-42 mm, usually pinkish; androecial base (11-)17-20 mm high, the outermost filaments 13-20 mm long, the anthers 2.5-3.5 mm long; ovary without wings, glabrous to puberulous, 4(-5)-locular, the summit usually puberulous with glabrous spots but sometimes tomentulose, the style conical, 2-4 mm long. Fruits globose, truncate at apex, the opercular region nearly as great in diam. as fruit diam., 3-7 x 4-7 cm, without persistent calyx lobes, first green then yellow-orange, the pericarp coriaceous, ca 0.5 mm thick, the mesocarp yellow, the opercular region slightly convex, apiculate. or umbonate. Seeds 1-3 per loculus, brown, angular in cross section, 20-30 x 20-30 mm; funicles straight (see image); aril absent.
Distribution: An understory tree from eastern Panama (Colón) to the Chocó of Colombia and Panama. The two subspecies are more or less sympatric.
Etymology: The specific epithet means dwarf which, most likely, is a reference to the small stature of this species.
